## Student Learning Outcomes

- The student will be able to analyze the forces, centroid and moments of inertia on structures, such as trusses, frames, beams, cables
- The student be able to determine the equilibrium of particles and rigid bodies in two and three dimensions

## Description

Principles of statics as applied to particles and rigid bodies in two and three dimensions under concentrated and distributed force systems.
